The present disclosure relates to a squirt container capable of varying the ratio of squirt volumes of two contents.

Conventionally, as a container for storing lotion, gray hair dye, etc., there has been proposed a squirt container configured to store two kinds of contents separately, mix them when used, and then squirt them (see, for example, Patent Document 1). ).

Japanese Patent No. 3651773

However, in the ejection container described in Patent Document 1, although it is possible to select whether to eject the same amount of the two types of contents at the same time or to eject only one of the contents, the ejection amount of the two types of contents is different. It was not possible to change the ratio and make it squirt. Therefore, it is difficult to finely adjust the ratio of the ejection amounts of the two contents according to the condition of the user's skin and hair, and there is room for improvement in this respect.

An object of the present disclosure is to solve such problems, and an object thereof is to provide a squirt container capable of changing the ratio of squirt amounts of two kinds of contents.

The ejection container of the present disclosure comprises:
two container bodies each capable of accommodating contents;
two pumps having two protruding stems that can be pushed downward in an upward biased state, and capable of pumping upward the contents in the two container bodies by pushing down the two stems;
an adjustment member that directly or indirectly presses the two stems and is rotatable around a substantially vertical axis positioned between the two container bodies in plan view;
a pressing head capable of rotating about a substantially horizontal axis parallel to the arrangement direction of the two container bodies by a pressing operation and pressing down the two stems via the adjusting member;
When the adjusting member is rotated around the substantially vertical axis, the plurality of pressing portions that directly or indirectly press the two stems of the adjusting member are among the plurality of pressing portions in plan view. As the pressing portion on one stem side approaches the substantially horizontal axis, the pressing stroke of the pressing portion on the one stem side due to the pressing operation of the pressing head is shortened, and the other stem of the plurality of pressing portions is pushed down. By moving the pressing portion on the side away from the substantially horizontal axis, the pushing down stroke of the pressing portion on the other stem side due to the pushing down operation of the pressing head becomes longer.

Further, in the ejection container of the present disclosure, in the configuration described above, the plurality of pressing portions of the adjusting member protrude downward from both ends of an arm portion extending in a substantially horizontal direction, and the adjusting member is positioned relative to the pressing head. It is preferable that it is mounted so as to be rotatable around the substantially vertical axis.

Further, in the ejection container of the present disclosure, in the configuration described above, the adjustment member has an operation lever that protrudes perpendicularly to the longitudinal direction of the arm portion and opposite to the substantially horizontal axis in a plan view, It is preferable that the operating lever protrudes substantially horizontally through a through hole provided in the pressing head.

Further, in the ejection container of the present disclosure, in the configuration described above, the adjustment member is connected to a knob provided on the upper surface of the pressing head, and the rotation can be adjusted by rotating the knob. is preferred.

Further, in the ejection container of the present disclosure, in the configuration described above, the two stems are individually attached with nozzle portions for guiding the respective contents pressure-fed from the two pumps to the corresponding ejection ports. Preferably, the member presses the two stems through the nozzle portion.

Further, in the ejection container of the present disclosure, in the configuration described above, it is preferable that the nozzle section has a concave portion recessed downward at an upper end portion on a side adjacent to the substantially horizontal axis line in a plan view.

Moreover, in the ejection container of the present disclosure, in the configuration described above, it is preferable that the nozzle section is connected to the ejection port via a flexible tube.

According to the present disclosure, it is possible to provide a squirt container capable of changing the ratio of the squirt amounts of two types of contents.

Hereinafter, the first embodiment of the present disclosure will be described more specifically with reference to the drawings.

As shown in FIGS. 1 and 2, the ejection container 100 of the present embodiment is used for containing, for example, cosmetics, hair dyes, etc. as contents (content liquid). The squirt container 100 of this embodiment includes a container body 10 that accommodates two types of contents for each content, a squirt cap 20 attached to a mouth portion 11 of the container body 10, and a squirt of the contents in the container body 10. A pump 30 for pressure-feeding to an outlet 52c, a nozzle section 50 having an ejection port 52c for ejecting contents, a head section 60 for operating the pump 30 by pressing operation, and an exterior covering the two container bodies 10 and the like from the outside. It includes a container 70, a connecting member 80 that connects two container bodies 10 and the like, and a lid body 90 that covers the nozzle portion 50 and the like.

In the present specification and the scope of claims, the vertical direction refers to the vertical direction when the ejection container 100 is in an upright position with the pressing head 63 positioned above the container body 10, as shown in FIG. shall mean direction. Further, the radial direction means a direction along a straight line that passes through the axis O of the ejection container 100 and is perpendicular to the axis O. As shown in FIG. In addition, the ejection container 100 of this embodiment includes two container bodies 10, an ejection cap 20, a pump 30, a nozzle portion 50, etc., and in the example of FIG. there is

The container body 10 is also called a delaminated container (delaminated container) or a double container, and has an outer layer body 18 and an inner layer body 17 accommodated inside the outer layer body 18, and contains contents (content liquid). It has a double structure in which the inner layer body 17 is independently deformed from the outer layer body 18 to reduce the volume according to the ejection of the liquid. Further, the mouth portion 11 of the container main body 10 is provided with an accommodating cylindrical portion 16 as a separate member, which covers the pump 30 to be described later from the outside in the radial direction and includes an internal plug member 19 .

The outer layer body 18 is a portion that constitutes the outer shell of the container body 10 . As shown in FIG. 2 , the outer layer body 18 is integrally connected to the cylindrical mouth portion 11 and the lower end of the mouth portion 11 , expands downward in diameter, and stretches outward in the radial direction with respect to the mouth portion 11 . a protruding shoulder portion 12, a substantially cylindrical body portion 13 integrally connected to the lower end of the shoulder portion 12, and a reduced diameter portion 14 having a diameter reduced radially inward from the body portion 13 at the lower end portion of the body portion 13; and a bottom portion 15 that closes the lower end portion of the reduced diameter portion 14 .

As shown in FIG. 1, the inner layer body 17 forms an accommodation space S for contents.

In this embodiment, the container body 10 is formed by co-extrusion of a synthetic resin material for the outer layer 18 and a synthetic resin material for the inner layer 17, which have low compatibility, to form a laminated parison. is used to form a laminate structure in which the inner layer 17 is releasably laminated on the inner surface of the outer layer 18 by blow molding. Note that the container body 10 can also be formed by biaxially stretching and blow-molding a preform having a laminated structure formed in advance by injection molding or the like.

In this embodiment, nylon is used as the material of the inner layer body 17 constituting the container body 10, and polypropylene (PP) is used as the material of the outer layer body 18. As shown in FIG. However, it is not limited to this mode, and the material of the inner layer 17 may be ethylene-vinyl alcohol copolymer resin (EVOH), and the material of the outer layer 18 may be high density polyethylene resin (HDPE) or low density polyethylene resin (HDPE). Polyethylene (LDPE) may also be used. Further, when forming a delaminated container by performing biaxial stretch blow molding, for example, polyethylene terephthalate (PET) may be used as the material of the outer layer body 18 . In addition, the materials of the inner layer body 17 and the outer layer body 18 are not limited to the materials described above, and other resins having low compatibility with each other may be used. Further, the container body 10 may be formed by separately forming and assembling the outer layer body 18 and the inner layer body 17 instead of the delaminated container. Although not shown, one or more Admers or the like extend vertically between the inner layer body 17 and the outer layer body 18 to partially join the inner layer body 17 and the outer layer body 18 . adhesive strips may be provided.

In this embodiment, the container body 10 is formed by blow molding, and air is introduced into the space between the outer layer body 18 and the inner layer body 17 via slits formed in the pinch-off portion of the bottom portion 15 . is configured to Then, when the content is ejected from the ejection port 52c, air is taken into the space between the outer layer body 18 and the inner layer body 17 from the outside via the slit by the amount of the ejected content, and the inner layer body 17 is reduced in volume and deformed. On the other hand, the outer layer body 18 can maintain its original shape. That is, when the outer layer body 18 is made of a material with relatively high rigidity such as polypropylene (PP), high density polyethylene resin (HDPE), or polyethylene terephthalate (PET), the outer layer body 18 is made of the inner layer body 17. The same shape can be maintained regardless of volume reduction deformation. Further, when the outer layer body 18 is made of a material with relatively low rigidity such as low-density polyethylene (LDPE), the volume-reducing deformation of the outer layer body 18 is temporarily caused by the volume-reducing deformation of the inner layer body 17. Even if there is a gap, the outer layer 18 can be restored to its original shape by taking air into the space between the outer layer 18 and the inner layer 17 via the slit.

With the above configuration, air is not taken into the inner layer body 17 from the outside, so deterioration of the quality of the contents due to oxidation or the like can be suppressed. In addition, the contents in the inner layer body 17 can be used up as much as possible to reduce the remaining amount, and even highly viscous contents can be discharged. Also, as will be described later, even if only a small amount of the content is ejected, air corresponding to the amount of ejection can be taken into the space between the outer layer body 18 and the inner layer body 17 via the slits.

As shown in FIG. 2, the outer peripheral surface of the mouth portion 11 is integrally provided with a male screw portion 11a for screwing the spout cap 20 thereon. The male threaded portion 11 a protrudes radially outward from the outer peripheral surface of the mouth portion 11 .

Further, the mouth portion 11 is provided with an inner plug member 19 (see FIG. 1), and a housing cylinder portion 16 is fixed to cover a lower assembly 31 of a pump 30 to be described later from the outside in the radial direction.

As shown in FIG. 2, the housing tube portion 16 includes a tubular portion 16a that covers the cylinder 33 from the outside in the radial direction, a flange portion 16b that continues to the upper end portion of the tubular portion 16a and protrudes radially outward, and the flange portion 16b. an upper outer wall 16c hanging downward from the outer end of the tubular portion 16a; A second diameter-reduced portion 16f (see FIG. 1) connected to the lower end of the first diameter-reduced portion 16e and having a diameter smaller than that of the first diameter-reduced portion 16e.

The upper end of the cylindrical portion 16a of the housing cylindrical portion 16 is fitted to the inner peripheral surface of the mouth portion 11 of the container body 10, and the mouth portion 11 is held between the upper end portion of the cylindrical portion 16a and the upper outer wall 16c. It is positioned and fixed to the container body 10 by sandwiching.

The inner plug member 19 is fitted and fixed to the inner surface of the first diameter-reduced portion 16e, and includes an inner plug 19a that blocks communication between the housing space S of the container body 10 and the outside before the ejection container 100 is assembled. (See the inner plug 19a indicated by the two-dot chain line in FIG. 1). When the cylinder 33 is pushed into the housing cylinder portion 16 when assembling the ejection container 100, the lower end of the fitting cylinder 33d presses the inner plug 19a, thereby forming a weakened portion connecting the inner plug 19a and the peripheral wall 19b. The inner plug 19a is broken and displaced to the position indicated by the solid line in FIG. As a result, the contents in the housing space S are pressure-fed upward by the pump 30 by pressing the pressing head 63, so that the contents can be ejected from the ejection port 52c.

Next, the configuration of the ejection cap 20 will be described.

The jet cap 20 is made of polypropylene, and as shown in FIG. It is formed in a substantially truncated cylindrical shape having a top wall 23 that extends downward. The jet cap 20 is attached to the container body 10 so that the outer peripheral wall 21 and the upper peripheral wall 22 cover the mouth portion 11 from the outside in the radial direction, and the top wall 23 covers the mouth portion 11 from above. Note that the ejection cap 20 may be made of other resin such as polyethylene.

An inner peripheral surface of the outer peripheral wall 21 is provided with a female threaded portion 21a. The female threaded portion 21a protrudes radially inward from the inner peripheral surface of the outer peripheral wall 21 and is configured to be threadably engaged with the male threaded portion 11a.

Peripheral ribs 22b extending vertically are intermittently provided on the outer peripheral surface of the upper peripheral wall 22 in the circumferential direction. The outer peripheral rib 22b enters between inner ribs 84a formed on the inner peripheral surface of the side wall portion 84 of the connecting member 80, which will be described later, and connects the connecting member 80 in the circumferential direction in a non-rotating state.

A fitting tube 23a is formed in the central portion of the top wall 23 of the ejection cap 20, and a communication hole 23b is provided inside the fitting tube 23a for communicating the top wall 23 vertically. As shown in FIG. 2, a stem 42 and a piston guide 44, which constitute an upper assembly 41 of the pump 30, which will be described later, extend vertically through the communication hole 23b. is conveyed to

Next, the configuration of the pump 30 will be described with reference to FIG. The pump 30 of this embodiment includes a lower assembly 31 fixed to the container body 10, and a vertically movable structure with respect to the lower assembly 31. The pump 30 is urged upward by an urging spring 49, and the head portion and an upper assembly 41 that moves downward under pressure from 60 and pumps the contents in the cylinder 33 .

As shown in FIG. 2, the lower assembly 31 of the pump 30 includes a cylinder 33 that stores the content from the storage space S, and a biasing spring 49 that is fitted to the inner peripheral surface of the upper end portion of the cylindrical portion 33a of the cylinder 33. and a suction valve member 35 having a suction valve 35 c and fitted to the inner peripheral surface of the cylinder 33 .

The cylinder 33 has a cylindrical portion 33a that stores the contents inside when the upper assembly 41 is biased upward, and is provided at the upper end portion of the cylindrical portion 33a. A flange portion 33b sandwiched between a fitting cylinder 33d integrally formed at the lower end of the cylindrical portion 33a via a stepped portion 33c and fitted to the inner peripheral surface of a blocking member 36, which will be described later, and a fitting cylinder 33d. It has a suction valve seat 33e which protrudes upward from the upper end of the cylinder 33d and closes the valve when the suction valve 35c is seated thereon.

The suction valve member 35 includes a suction valve 35c elastically supported by a support member 35d, a support base 35a supporting the suction valve 35c, and an upper wall 35b closing the upper end of the support base 35a. The support bases 35a are intermittently formed in the circumferential direction, and when the suction valve 35c is displaced upward by the negative pressure in the cylinder 33 and the valve is opened, the contents in the accommodation space S are fitted. It passes through the interior of the cylinder 33d, the space between the suction valve 35c and the suction valve seat 33e, and the space between the intermittently provided support bases 35a to enter the cylindrical portion 33a of the cylinder 33. flow into

As shown in FIG. 2, the upper assembly 41 of the pump 30 includes a cylindrical stem 42 that transmits the pressing force from the pressing head 63 and the outer peripheral surface of the upper end of the stem 42 that is fitted to the upper end of a biasing spring 49 . a piston guide 44 having a guide body 44a fitted to the inner peripheral surface of the stem 42 and having a discharge valve hole 44c and a discharge valve seat 44d; It has an annular piston 43 that slides on the inner peripheral surface of 33a and moves up and down.

The stem 42 has a connecting tube portion 42a which forms a moving space for the contents therein and has an upper end to which the nozzle portion 50 is fitted. and an enlarged diameter portion 42c having a larger diameter than 42a. A piston guide 44 is fitted inside the connecting tube portion 42 a , and the upper end of the connecting tube portion 42 a is fitted to a first locking member 46 that holds the upper end of a biasing spring 49 . Further, the inner wall upper end portion 43b of the annular piston 43 is slidably configured on the inner peripheral surface of the enlarged diameter portion 42c. A lower end portion 43c of the inner wall of the annular piston 43 constitutes a discharge valve together with a discharge valve seat 44d. That is, when the inner wall lower end portion 43c is seated on the discharge valve seat 44d, the discharge valve is closed, and when the inner wall lower end portion 43c is separated from the discharge valve seat 44d, the discharge valve is opened to discharge the contents. It becomes possible to pass through the valve hole 44c. The outer wall 43a of the annular piston 43 slides on the inner surface of the tubular portion 33a of the cylinder 33. As shown in FIG.

Next, the nozzle part 50 will be explained. The nozzle part 50 has a mounting member 51 fitted to the upper end of the stem 42 and guiding the contents pumped from the pump 30 to a jetting port 52c, and a jetting port 52c of the contents mounted at the tip of the mounting member 51. and a spout member 52 provided.

The mounting member 51 includes a vertical cylindrical portion 51a that forms a flow path for guiding the contents upward and is fitted to the upper end of the stem 42, and a vertical cylindrical portion 51a perpendicular to the vertical cylindrical portion 51a that allows the contents to flow horizontally to the ejection port 52c. A horizontal cylindrical portion 51d for guiding, a ceiling wall 51b connected to the upper end of the vertical cylindrical portion 51a, a peripheral wall 51c hanging down from the outer peripheral end of the ceiling wall 51b, and an adjusting member 61 provided above the vertical cylindrical portion 51a and described later. It has a pressure receiving portion 51e with which the portion 61b abuts. The horizontal tubular portion 51d is oriented in a direction from both left and right sides toward the center in a front view shown in FIGS. Then, the two types of contents pressure-fed from the two container bodies 10 are led to the center and ejected forward from the two adjacent ejection ports 52c (in the direction perpendicular to the paper surface of FIGS. 1 and 2, from the back to the front). Let

The ejection port member 52 includes a fitting tube portion 52a into which the outer peripheral surface of the horizontal tube portion 51d is fitted, and an ejection port tube portion 52b that guides forward the contents that have passed through the horizontal tube portion 51d. An ejection port 52c is formed inside the ejection port cylindrical portion 52b. 3 and 4 show a front view and a plan view of the ejection container 100 including the ejection port member 52. FIG.

Next, the head section 60 will be described. The head portion 60 includes an adjusting member 61 that presses down the pressure receiving portions 51e of the two mounting members 51 at a stroke ratio desired by the user, and a pressing head 63 that applies a pressing force to the adjusting member 61 .

As shown in FIGS. 5, 6A, and 6B, the adjustment member 61 includes an arm portion 61e extending in the left-right direction (the left-right direction in FIGS. 1 and 2 and the up-down direction in FIG. 5) and both longitudinal ends of the arm portion 61e. and an operating lever 61f extending perpendicular to the longitudinal direction of the arm portion 61e and projecting to the side facing the substantially horizontal axis OH shown in FIG. The adjusting member 61 is attached to the pressing head 63 by fitting a rotating shaft 63b (see FIGS. 5 and 7B) provided in the pressing head 63 into a rotating hole 61d of the adjusting member 61. It is rotatable around an axis 63b (substantially vertical axis OV).

As shown in FIG. 5, the pressure receiving portion 51e of the mounting member 51 is provided in a shape along the trajectory of the pressing portion 61b when the adjusting member 61 rotates around the substantially vertical axis OV. Further, as shown in FIG. 5, the pressure receiving portion 51e has a pressure receiving portion 51e on the side adjacent to the axis (substantially horizontal axis OH) that is the center of rotation of the pressing head 63 when the pressing head 63 is pressed downward. A recess 51f recessed downward from the height of is formed. In the example of FIG. 5, a concave portion 51f having a height equal to the height of the upper surface of the ceiling wall 51b is provided on the side adjacent to the substantially horizontal axis OH of the pressure receiving portion 51e.

The rotary shaft 63 c of the pressing head 63 is configured to be rotatable around a rotary groove (not shown) provided in the connecting member 80 . Therefore, when the pressing head 63 is pushed down in the direction of the arrow shown in FIG. 8, the pressing head 63 rotates around the rotary shaft 63c (substantially horizontal axis OH). Therefore, the larger the distance (horizontal distance in FIGS. 5 and 8) between the rotating shaft 63c (substantially horizontal axis OH) and the pressing portion 61b in plan view, the greater the distance when the pressing head 63 rotates by the same angle. The stroke of the pressing portion 61b pressed by the pressing plate 63a via the contact portion 61g is increased (see FIGS. 5 and 8). Therefore, the stroke of the stem 42 pressed by the pressing portion 61b also increases. Therefore, in FIG. 5, when the adjustment member 61 is rotated around the substantially vertical axis OV to vary the distances (horizontal distances in FIGS. 5 and 8) from the substantially horizontal axis OH of the two pressing portions 61b, , the amount of contents ejected by the stem 42 (pump 30) pressed by the pressing portion 61b having a greater distance from the substantially horizontal axis OH can be relatively increased. Therefore, the ratio of the ejection amounts of the two types of contents can be changed.

In particular, as shown in FIGS. 9 and 10, when one of the pressing portions 61b is above the recessed portion 51f, even if the pressing head 63 is pressed, the pressing portion 61b above the recessed portion 51f does not press the mounting member 51. Therefore, the pump 30 on the side where the pressing portion 61b is above the recessed portion 51f does not operate. Therefore, since only the other pump 30 operates, only one of the two types of contents can be selectively ejected.

As shown in FIG. 11, the adjusting member 61 can be rotated around the vertical axis OV by gripping an operation lever 61f provided on the adjusting member 61 and moving it in the horizontal direction indicated by the arrow. It can be done by rotating it. In the illustrated example, the operation lever 61f can be easily grasped by penetrating the through hole 63h (see FIGS. 7A and 7B) provided in the pressing head 63 and protruding in the horizontal direction. , the adjustment member 61 can be easily operated.

The outer container 70 has a size that accommodates the two container bodies 10 , and includes a side wall portion 71 and a bottom portion 72 that closes the lower end of the side wall portion 71 . The bottom portion 72 is provided with two positioning walls 73 for accommodating and positioning the diameter-reduced portion 14 of the container body 10 .

A connecting member 80 for connecting and positioning the two ejection caps 20 is fitted to the inner peripheral surface of the upper end portion of the outer container 70 . The connection member 80 includes a side wall portion 84 surrounding the outer peripheral wall 21 of the ejection cap 20 , an upper wall 82 continuing to the upper end portion of the side wall portion 84 and connecting the two ejection caps 20 , and an upper wall 82 extending upward from the outer peripheral end of the upper wall 82 . an extending peripheral wall 81, two upper cylinder walls 83 extending upward from the upper surface of the upper wall 82 and surrounding each nozzle portion 50 from the outside in the radial direction; A partition wall 85 is provided. As shown in FIG. 1, the fitting cylinder 23a of the ejection cap 20 is fitted to the inner peripheral surface of the upper cylinder wall 83, so that the ejection cap 20 is secured to the connecting member 80 in the vertical direction. In addition, the outer peripheral rib 22b of the ejection cap 20 enters between the inner ribs 84a formed on the inner peripheral surface of the side wall portion 84 of the connecting member 80, so that the ejection cap 20 is prevented from turning around the connecting member 80. Fixed.

The lid body 90 includes an outer peripheral wall 91 that covers the nozzle portion 50 and the head portion 60 from the outside in the radial direction, and an upper wall 92 that continues to the upper end portion of the outer peripheral wall 91 . Further, the outer peripheral wall 91 is fixed to the connecting member 80 by fitting the lower end portion of the outer peripheral wall 91 into the inner peripheral surface of the peripheral wall 81 . The lid body 90 covers the area above the connecting member 80 from the radially outer side and above except for the upper surface of the pressing head 63 . The outer peripheral wall 91 of the lid body 90 is configured to substantially overlap the peripheral wall 81 of the connecting member 80 and the side wall portion 71 of the outer container 70 in plan view.

In order to eject the contents from the ejection container 100 having the above configuration, the user first presses down the pressing head 63 from the upright state of the ejection container 100 shown in FIG. At this time, the pressing head 63 rotates around the substantially horizontal axis OH shown in FIGS. 5 and 8, and pushes each pressing portion 61b with a stroke substantially proportional to the horizontal distance between the substantially horizontal axis OH and each pressing portion 61b. Press 61b. Therefore, when the user rotates the adjustment member 61 around the substantially vertical axis OV from the state shown in FIGS. , the stroke with which each pressing portion 61b presses down the corresponding stem 42 can be made different. Therefore, the two types of contents in the container body 10 corresponding to each stem 42 can be ejected with different ratios of ejection amounts.

When the stem 42 constituting the upper assembly 41 of the pump 30 is pushed down by pushing down the push head 63, the piston guide 44 fitted and fixed to the inner peripheral surface of the stem 42 also moves downward at the same time. At this time, the upper end portion 43b of the inner wall of the ring-shaped piston 43 slides on the inner peripheral surface of the enlarged diameter portion 42c, so that it is only slightly displaced. Accordingly, since the discharge valve seat 44d of the piston guide 44 is separated from the inner wall lower end portion 43c of the annular piston 43, the discharge valve is temporarily opened.

As the lower end portion 44e of the piston guide 44 is displaced downward, the contents stored in the cylinder 33 are compressed, pass through the opened discharge valve, and flow into the piston guide 44 through the discharge valve hole 44c. pumped upwards. The stem 42 moves downward by a distance corresponding to the pressing stroke of the pressing portion 61b, but stops at a position where the lower end portion 44e of the piston guide 44 contacts the upper wall 35b of the suction valve member 35 at the maximum. As is clear from FIG. 2 and the like, the larger the stroke of the stem 42 and the further downward the piston guide 44 is displaced, the larger the volume of the contents pumped upward through the discharge valve. can be ejected.

When the user stops pressing the pressing head 63 , the restoring force of the biasing spring 49 pushes back the first locking member 46 upward. As a result, the stem 42 fitted to the inner peripheral surface of the first locking member 46 is also pulled upward together with the piston guide 44, so that the pressure inside the cylinder 33 changes to negative pressure. Further, immediately after the stem 42 and the piston guide 44 start to move upward, the lower end 43c of the inner wall of the ring-shaped piston 43 is not seated on the discharge valve seat 44d. Of the contents in the passage up to , the contents corresponding to the volume change in the cylinder 33 are sucked downward by the negative pressure. This effect, also called the suck-back effect, causes the contents remaining in the passage to be sucked into the cylinder 33, suppressing dripping from the spout 52c. Further, as the piston guide 44 continues to rise, the discharge valve seat 44d abuts against the lower end portion 43c of the inner wall and is sealed, closing the discharge valve. As the discharge valve is closed, the suction valve 35c of the suction valve member 35 is lifted up by the negative pressure described above against its own weight and the elastic force of the support member 35d, and the suction valve 35c is opened. The contents in the accommodation space S are sucked up by the negative pressure in the cylinder 33, pass through the suction valve 35c, pass through the space between the supports 35a, and are stored in the cylinder 33.

When the stem 42 reaches the highest point of its movable range, the suction of the contents from the housing space S into the cylinder 33 is finished, and the suction valve 35c is again seated on the suction valve seat 33e. At this time, the inner layer body 17 is reduced in volume and deformed as the content in the accommodation space S is reduced, but air is not taken into the inner layer body 17 from the outside because the suction valve 35c is closed. Therefore, deterioration of the quality of the content due to oxidation or the like can be suppressed. Further, since air is introduced into the space between the outer layer 18 and the inner layer 17 through the slit formed in the bottom portion 15 of the container body 10, the outer layer 18 remains in its original state even if the inner layer 17 is reduced in volume and deformed. It can maintain its shape. In particular, by changing the ejection ratio of the two types of contents, even if the ejection amount of one of the contents is small, the amount of air corresponding to the small ejection amount is passed through the slits in the bottom portion 15 and the outer layer body 18. It is introduced into the space between the inner layer body 17 . Therefore, the outer layer body 18 can easily maintain its original shape.

As described above, in this embodiment, there are two container bodies 10 each capable of accommodating a content, and two stems 42 protruding so that they can be pushed down in an upwardly biased state. The two pumps 30 capable of pumping the contents in the two container bodies 10 upward, and the two stems 42 are directly or indirectly pressed to position between the two container bodies 10 in plan view. and an adjusting member 61 rotatable about a substantially vertical axis OV, and an adjusting member 61 that rotates about a substantially horizontal axis OH parallel to the arrangement direction of the two container bodies 10 by pushing down the two stems. A plurality of pressing portions 61b that directly or indirectly press the two stems 42 of the adjusting member 61 rotate the adjusting member 61 around the substantially vertical axis OV. Then, one stem-side pressing portion 61b of the plurality of pressing portions 61b approaches the substantially horizontal axis OH in plan view, so that the pressing-down stroke of one stem-side pressing portion 61b due to the pressing-down operation of the pressing head 63 is increased. The other stem-side pressing portion 61b of the plurality of pressing portions 61b moves away from the substantially horizontal axis OH, so that the pressing-down stroke of the other stem-side pressing portion 61b due to the pressing-down operation of the pressing head 63 becomes longer. configured as By adopting such a configuration, by adjusting the rotation of the adjusting member 61 before pushing down the pressing head 63 and ejecting the contents, it is possible to change the ejection amount ratio of the two types of contents and eject them. can. In particular, in this embodiment, since the ratio of the ejection amounts can be adjusted by adjusting the rotation of the adjusting member 61, the ejection amounts of the two types of contents can be adjusted without changing the relative positions of the container body 10 and the ejection port 52c. You can change the ratio and squirt.

Further, in this embodiment, the plurality of pressing portions 61b of the adjusting member 61 protrude downward from both ends of the arm portion 61e extending substantially horizontally, and the adjusting member 61 is positioned substantially vertically with respect to the pressing head 63. It was configured to be rotatably mounted around the OV. By adopting such a configuration, the adjusting member 61 can be made compact, and the stem 42 can be reliably pushed down by the pressing portion 61b projecting downward to operate the pump 30. As shown in FIG.

In the present embodiment, the adjustment member 61 has an operation lever 61f protruding perpendicularly to the longitudinal direction of the arm portion 61e and facing the substantially horizontal axis OH in plan view. It is configured to pass through a through hole 63h provided in the pressing head 63 and protrude in a substantially horizontal direction. By adopting such a configuration, the adjusting member 61 arranged between the pressing head 63 and the stem 42 can be easily rotated and adjusted using the operating lever 61f.

Further, in this embodiment, the two stems 42 are individually attached with the nozzle portions 50 that guide the respective contents pumped from the two pumps 30 to the corresponding ejection ports 52c. It is configured to press the two stems 42 through the portion 50 . By adopting such a configuration, compared with the case where the adjusting member 61 directly presses the stem 42, the stem 42 can be pressed more easily. The contents can be easily guided up to.

Further, in the present embodiment, the nozzle portion 50 is configured such that a concave portion 51f recessed downward is formed at the upper end portion on the side adjacent to the substantially horizontal axis OH in plan view. By adopting such a configuration, it is possible to easily create a state in which one of the contents is not ejected.

Next, a specific example of the ejection container 200 according to the second embodiment of the present disclosure will be described with reference to the drawings.

Note that, unlike the first embodiment, the ejection container 200 according to the second embodiment realizes the functions of the ejection cap 20 and the connecting member 80 only with the ejection cap 120, and the attachment member in the nozzle section 50. 51 and the ejection port member 52 are realized by the mounting member 151, the ejection port member 152, and the flexible tube 153 of the nozzle portion 150, and the functions of the adjustment member 61 and the operation lever 61f in the head portion 60 are Except for the points realized by the adjustment member 161 and the knob portion 165 of the head portion 160, and the point that the pipe P is fitted inside the second diameter-reduced portion 16f of the housing tube portion 16, the first embodiment is similar to Therefore, here, the description will focus on the differences from the first embodiment.

The ejection cap 120 of this embodiment is made of polypropylene, and as shown in FIG. A peripheral wall 125 having a rectangular shape and surrounding the two inner peripheral walls 121 from the outside, a top wall 123 connected to the upper ends of the inner peripheral wall 121 and the outer peripheral wall 125, and extending further upward from the top surface of the top wall 123, the lid An upper peripheral wall 127 for fitting the inner peripheral surface of the lower end portion of the outer peripheral wall 91 of the body 90 to mount the lid body 90 is provided. The ejection cap 120 is attached to the container body 10 so that the inner peripheral wall 121 covers the mouth portion 11 from the outside in the radial direction, and the top wall 123 covers the mouth portion 11 from above. Note that the ejection cap 120 may be made of other resin such as polyethylene.

The inner peripheral surface of the inner peripheral wall 121 is provided with a female screw portion 121a. The female threaded portion 121a protrudes radially inward from the inner peripheral surface of the inner peripheral wall 121 and is configured to be threadably engaged with the male threaded portion 11a.

The upper end portion of the side wall portion 71 of the outer container 70 is fitted to the inner peripheral surface of the lower end portion of the outer peripheral wall 125 . The outer peripheral wall 125 has a substantially rectangular shape that generally overlaps with the outer peripheral wall 91 of the lid 90 and the side wall portion 71 of the outer container 70 in plan view. As a result, the ejection container 200 has a prismatic outer shape having substantially the same cross-sectional shape in a plan view from the lid 90 to the outer container 70 .

The top wall 123 of the ejection cap 120 is provided with two communicating holes 123b. As shown in FIG. 12, the stem 42 and the piston guide 44 that constitute the upper assembly 41 of the pump 30 extend vertically through the communication hole 123b, and the pressing force from the head portion 160 is transmitted to the pump 30. are doing.

Next, the nozzle section 150 will be described. The nozzle portion 150 is fitted to the upper end portion of the stem 42 and is attached to a mounting member 151 that guides the contents pumped from the pump 30 to the ejection port 152c, and to the horizontal cylindrical portion 151d of the mounting member 151. and a jetting port member 152, and a jetting port member 152 having a content jetting port 152c.

The mounting member 151 includes a vertical tubular portion 151a that forms a channel for guiding the contents upward and is fitted to the upper end of the stem 42, and a horizontal tubular portion 151d that is orthogonal to the vertical tubular portion 151a and guides the contents in the horizontal direction. and a pressure receiving portion 151e which is provided above the vertical cylindrical portion 151a and abuts against a pressing portion 161b of an adjusting member 161, which will be described later. The horizontal cylindrical portion 151d is oriented in a direction perpendicular to the plane of the paper when viewed from the front shown in FIG.

The horizontal tubular portion 151d is connected to the fitting tubular portion 152a of the ejection port member 152 by a flexible tube 153, as shown in FIGS. 12 and 13B. The flexible tube 153 is bent at about 90 degrees as shown in FIG. 13B, and guides the content discharged forward from the horizontal tubular portion 151d to flow in from the left and right side surfaces of the ejection port member 152. there is

The ejection port member 152 includes a fitting tubular portion 152a for fitting the outer peripheral surface of the flexible tube 153, and an ejection port tubular portion 152b for guiding the contents forward. An ejection port 152c is formed inside the ejection port cylindrical portion 152b. 13A and 15 show a plan view and a front view of the ejection container 200 including the ejection port member 152. FIG.

By connecting the mounting member 151 and the ejection port member 152 via the flexible tube 153 in this way, the mounting member 151 can be pushed downward by pressing the pressing head 163 as shown in FIG. Even in the case of a large displacement, the flexible tube 153 absorbs relative height fluctuations between the mounting member 151 and the ejection port member 152, so the ejection port member 152 can be maintained at the same position without tilting. .

Next, the head section 160 will be described. The head portion 160 includes an adjusting member 161 that presses down the pressure receiving portions 151e of the two mounting members 151 at a stroke ratio desired by the user, and a pressing head 163 that applies a pressing force to the adjusting member 161 .

As shown in FIGS. 13B and 14, the adjusting member 161 has a prismatic shape, and its lower surface constitutes a pressing portion 161b. The adjusting member 161 has a rotating shaft 161d protruding upward from the central upper surface in the longitudinal direction. (See FIG. 12). The rotary shaft 161d is fitted to the knob portion 165 on the upper surface of the pressing plate 163a. By rotating the knob portion 165 in the circumferential direction, the adjustment member 161 is rotated around the rotary shaft 161d (substantially vertical axis OV). It is rotatable. In this embodiment, as shown in FIGS. 18 and 20, which will be described later, the mounting member 151 is configured to be able to be pressed at two longitudinal ends of the lower surface of the adjusting member 161 . In this sense, the adjusting member 161 has two pressing portions 161b.

As shown in FIG. 14, the pressing head 163 is integrally formed with the lid body 90 and is configured to be rotatable around the hinge portion 163c. Accordingly, when the pressing plate 163a of the pressing head 163 is pressed, the pressing head 163 rotates around the hinge portion 163c (substantially horizontal axis OH). Therefore, of the pressing portion 161b on the lower surface of the adjusting member 161, the portion that actually presses the pressure receiving portion 151e of the mounting member 151 and the hinge portion 163c (substantially horizontal axis OH) are separated from each other by the horizontal distance (horizontal distance in FIG. 14). ) increases, the stroke of the pressing portion 161b pressed by the pressing plate 163a when the pressing head 163 rotates by the same angle increases. Therefore, the stroke of the stem 42 pressed by the pressing portion 161b also increases. 12 to 15 show a locked state in which even if the pressing head 163 is pressed down, the pressing head 163 and the adjusting member 161 do not contact each other and the stem 42 is not pressed down.

FIG. 16 shows a state in which the knob portion 165 is rotated counterclockwise by 55 degrees in plan view from the locked state shown in FIG. 13B. As a result of the rotation of the adjustment member 161 interlocking with the rotation of the knob 165, the adjustment member 161 and the mounting member 151 do not overlap at all on the A container side located at the bottom in FIG. 16, the adjusting member 161 and the mounting member 151 overlap each other in plan view, and the mounting member 151 can be pressed by the pressing head 163. As shown in FIG.

17A and 17B are right side sectional views of the ejection container 200 in the state shown in FIG. 16. FIG. FIG. 17A shows a cross-sectional view of the A container side, and even if the pressing head 163 is pressed and rotated around the hinge portion 163c (substantially horizontal axis OH), the adjusting member 161 and the mounting member 151 do not move in plan view. Since there is no overlap, the mounting member 151 is not pressed. Therefore, the contents are not ejected from the A container side. On the other hand, on the B container side shown in FIG. , and the stem 42 on the B container side is also pressed. Therefore, the contents are ejected from the B container side. Thus, at the position of the adjusting member 161 shown in FIGS. 16, 17A, and 17B, the ratio of the ejection amount of the contents can be set to 0:100.

FIG. 18 shows a state in which the knob portion 165 is rotated counterclockwise by 76 degrees in plan view from the locked state shown in FIG. 13B. As a result of the rotation of the adjustment member 161 interlocking with the rotation of the knob 165, the adjustment member 161 and the mounting member 151 are mounted on both the A container side located at the bottom in FIG. 18 and the B container side located at the top in FIG. are overlapped in a plan view, and both mounting members 151 can be pressed by the pressing head 163 .

However, as can be seen from FIG. 18, the portion of the pressing portion 161b of the adjusting member 161 on the A container side that overlaps with the pressure receiving portion 151e of the mounting member 151 does not overlap with the pressure receiving portion 151e of the mounting member 151 on the B container side. The distance from the hinge portion 163c (substantially horizontal axis OH) is smaller than that of the portion overlapping the pressure receiving portion 151e. Therefore, the stroke amount by which the pressing head 163 presses the mounting member 151 via the adjusting member 161 when the pressing head 163 is pressed and rotated around the hinge portion 163c (substantially horizontal axis OH) is shown in FIGS. As can be seen from the comparison in FIG. 19B, the A container side is 2.7 mm, the B container side is 3.9 mm, and the A container side is smaller. Therefore, the amount of depression of the stem 42 on the A container side can be made smaller than the amount of depression of the stem 42 on the B container side. can be less than quantity. According to the applicant's study, the ejection amount on the A container side: the ejection amount on the B container side was 30:70.

FIG. 20 shows a state in which the knob portion 165 is rotated counterclockwise by 90 degrees in plan view from the locked state shown in FIG. 13B. As a result of the rotation of the adjustment member 161 interlocking with the rotation of the knob 165, the adjustment member 161 and the mounting member 151 are aligned on both the A container side located at the bottom in FIG. 20 and the B container side located at the top in FIG. are overlapped by the same area in a plan view, and both mounting members 151 can be pressed by pressing of the pressing head 163 .

Moreover, the portion of the pressing portion 161b of the adjusting member 161 on the A container side that overlaps with the pressure receiving portion 151e of the mounting member 151 is the portion of the pressing portion 161b of the adjusting member 161 that overlaps with the pressure receiving portion 151e of the mounting member 151 on the B container side. , the distance from the hinge portion 163c (substantially horizontal axis OH) is the same. Therefore, the stroke amount by which the pressing head 163 presses the mounting member 151 via the adjusting member 161 when the pressing head 163 is pressed and rotated around the hinge portion 163c (substantially horizontal axis OH) is shown in FIGS. As can be seen from the comparison of FIG. 21B, both the A container side and the B container side are equal at 3.15 mm. Therefore, the amount of depression of the stem 42 on the A container side can be approximately equal to the amount of depression of the stem 42 on the B container side. can be approximately equal to the amount

As described above, in the present embodiment, the adjusting member 161 is connected to the knob 165 provided on the upper surface of the pressing head 163, and can be rotated and adjusted by rotating the knob 165. Configured. By adopting such a configuration, the adjusting member 161 arranged between the pressing head 163 and the mounting member 151 can be adjusted by a simple operation of rotating the knob portion 165 provided on the pressing head 163. be able to.

Further, in this embodiment, the nozzle part 150 is configured to be connected to the ejection port 152c via the flexible tube 153. As shown in FIG. By adopting such a configuration, even if the nozzle portion 150 (mounting member 151) is displaced greatly downward due to the pressing of the pressing head 163, the flexible tube 153 is connected to the mounting member 151 and the ejection port 152c (ejection port 152c). Since the relative height variation with the member 152) is absorbed, the ejection port 152c can be maintained at the same position without tilting.

Next, a specific example of the ejection container 300 according to the third embodiment of the present disclosure will be described with reference to the drawings.

Note that, in the ejection container 300 according to the third embodiment, in comparison with the first embodiment, the functions of the ejection cap 20 and the connecting member 80 are realized only by the ejection cap 220, and the adjusting member in the head portion 60 61 and the operation lever 61f are realized by the adjustment member 261 and the operation portion 261f of the head portion 260, and the outer container 70 is not separately provided around the container body 10. Similar to morphology. Therefore, here, the description will focus on the differences from the first embodiment.

The ejection cap 220 of the present embodiment is made of polypropylene, has a rectangular shape with rounded corners in plan view (see FIG. 24), and is attached to the mouth portions 11 of the two container bodies 10, respectively. a top wall 223 that continues to the upper end of the peripheral wall 221; an upper peripheral wall 227 that extends further upward from the upper surface of the top wall 223; and an engaging protrusion 227a for engaging with the inner peripheral surface of the lower portion of the lid body 90 to mount the lid body 90 thereon. The ejection cap 220 is attached to the container body 10 so that the peripheral wall 221 covers the mouth portion 11 from the outside in the radial direction, and the top wall 223 covers the mouth portion 11 from above. Note that the ejection cap 220 may be made of other resin such as polyethylene.

A female screw portion 221 a is provided on the inner peripheral surface of the peripheral wall 221 . The female threaded portion 221a protrudes radially inward from the inner peripheral surface of the peripheral wall 221 and is configured to be threadably engaged with the male threaded portion 11a.

The top wall 223 of the ejection cap 220 is provided with two communication holes 223b. As shown in FIG. 22 , the upper portion of the pump 30 extends vertically through the communication hole 223 b to transmit the pressing force from the head portion 260 to the pump 30 .

Next, the head section 260 will be described. The head portion 260 includes an adjusting member 261 for pressing down the pressure receiving portions 51e of the two mounting members 51 of the nozzle portion 50 at a stroke ratio desired by the user, and an approximately horizontal axis OH ( 25), and a pressing head 263 capable of pressing down the two stems 42 via an adjusting member 261. As shown in FIG.

In this embodiment, the pressing head 263 is pushed down by pressing the operating portion 261f of the adjusting member 261 downward. As described above, the pressing operation of the pressing head 263 is not limited to the case of directly pressing down the pressing head 263, and the pressing head 263 is indirectly pressed down by applying force to another member as in the present embodiment. It is a concept that includes cases.

As shown in FIG. 25, the adjusting member 261 includes an arm portion 261e extending in the left-right direction (the left-right direction in FIG. 22 and the up-down direction in FIG. 25) and pressing portions formed on the lower surfaces of both longitudinal ends of the arm portion 261e. 261b, a fitting projection 261g projecting in the left-right direction (vertical direction in FIG. 25) from the upper portion of the pressing portion 261b, and a disk-shaped operating portion 261f provided in the center of the adjusting member 261 in the longitudinal direction. there is As shown in FIG. 22, the adjusting member 261 is attached to the pressing head 263 by fitting a rotating shaft 261d of the adjusting member 261 into a rotating hole 263b provided in the pressing head 263. 263b (substantially vertical axis OV) (see FIG. 25).

The pressing head 263 includes a rotary shaft 263c defining a substantially horizontal axis OH, positioning arms 263a extending rearward from both ends of the rotary shaft 263c in the horizontal direction (vertical direction in FIG. 25), and the aforementioned rotary hole 263b. and

A rotating shaft 263 c of the pressing head 263 is configured to be rotatable around a sliding surface (not shown) provided on the lid body 90 . Therefore, when the pressing head 263 is pushed down in the direction toward the back of the paper surface of FIG. 25 via the operating portion 261f, the pressing head 263 rotates around the rotation shaft 263c (substantially horizontal axis OH). Therefore, when the pressing head 263 rotates by the same angle, the larger the distance (left-right direction distance in FIG. 25) between the rotating shaft 263c (substantially horizontal axis OH) and the pressing portion 261b in plan view, the more pressed it is. The stroke of the pressing portion 261b increases. Accordingly, the stroke of the stem 42 pressed by the pressing portion 261b also increases. Therefore, in FIG. 25, when the adjustment member 261 is rotated about the substantially vertical axis OV to change the distances of the two pressing portions 261b from the substantially horizontal axis OH (horizontal distance in FIG. 25), the substantially horizontal It is possible to relatively increase the amount of the contents ejected by the stem 42 (pump 30) pressed by the pressing portion 261b having a greater distance from the directional axis OH. Therefore, the ratio of the ejection amounts of the two types of contents can be changed.

In the present embodiment, adjustment of the rotation of the adjustment member 261 about the vertical axis OV is performed by rotating the operating portion 261f shown in FIGS. 22 and 25 about the vertical axis OV. As a result, the arm portion 261e of the adjusting member 261 and the pressing portion 261b provided at the tip of the arm portion 261e rotate about the substantially vertical axis OV, so that the distance between the two pressing portions 261b from the substantially horizontal axis OH is (left-right direction distance in FIG. 25) can be changed respectively.

In the present embodiment, the fitting projection 261g provided on the upper portion of the pressing portion 261b is fitted into one of the plurality of recesses 263d provided on the positioning arm 263a of the pressing head 263, so that the pressing portion 261b can be pressed. An angular position about the substantially vertical axis OV of the adjustment member 261 relative to the head 263 is positioned. The user rotates the operating portion 261f further around the vertical axis OV to fit the fitting protrusion 261g into another recess 263d, thereby adjusting the adjusting member 261 relative to the pressing head 263 to the substantially vertical axis OV. Angular position around can be changed. This makes it possible to change the ratio of the ejection amounts of the two types of contents.

By fitting the fitting projection 261g into the recess 263d in this manner, the user can easily recognize that the adjustment member 261 has been adjusted to the intended angular position. In addition, it is possible to suppress the angular positional deviation of the adjustment member 261 not intended by the user.
